Abstract (en)
[origin: WO2021078837A1] The invention relates to a process for the manufacture of hybrid products comprising at least two different elastomer materials bonded to each other, said at least two different elastomer materials being based on at least one rubber of the ethylene propylene diene monomer (EPDM) type and at least one rubber of the silicone type wherein the silicone rubber comprises alkenyl functionalized polydialkylsiloxanes. The inventive process is particularly useful for the manufacture of EPDM-silicone hybrid sealing profiles.
